Naloxone Nasal Spray Works Best to Stop Opioid OD: Study

Increased public availability of naloxone, also known by the brand name Narcan, is considered a key way to reduce opioid overdose deaths. But there’s more than one way to administer it, and it wasn’t clear which method would be most successful when given by a bystander.

In this study, 138 adults watched a two-minute video demonstrating how to administer naloxone using one of the three methods — two nasal sprays and one intramuscular shot. Each participant then selected one method to administer naloxone to a mannequin.

The study participants had a higher rate of success with the single-step nasal spray than with an intramuscular naloxone injection. They administered the one-step nasal spray faster than either a multi-step atomized spray or shot.

“With training, nasal sprays in general had a higher degree of success than the shot,” said study author William Eggleston. He’s a clinical assistant professor in the School of Pharmacy and Pharmaceutical Sciences at Binghamton University in New York.

“Even if it seemed to us it was a no-brainer that we should be using nasal sprays, we had no data before, so now we have some to support that,” he said in a university news release.

The study was published in the August issue of the journal Addiction.
